Fiberglass Insulation Manufacturer Tackles Installation Quality

Posted on April 26,2015 by ab3 in fiberglass batt

One of the major fiberglass insulation manufacturers (the color in the lead photo gives away which one I'm talking about) is getting serious about the installation quality of fiberglass batt insulation. They've put out a video (embedded below) and a document showing how to achieve RESNET Grade 1 installation quality with fiberglass batts. Have you seen these things yet?

Owens Corning Buys Mineral Wool Manufacturer

Posted on April 26,2015 by ScottG in fiberglass insulation

Owens Corning is going into the mineral wool insulation business. The Toledo, Ohio, company has purchased Thermafiber Inc., a manufacturer of mineral wool insulation for residential, commercial, and industrial markets. Owens Corning already makes a variety of insulation products, including its familiar pink fiberglass batts, blown-in fiberglass, extruded polystyrene, and duct liner and duct board. Thermafiber has a single 145,000-sq. ft. plant in Wabash, Indiana, with about 150 employees. Owens Corning would not say how much insulation the plant currently produces.

Batt Insulation is Still Making Me Batty

I recently performed the pre-drywall inspection on a small home seeking LEED certification. The local building inspector had visited and approved the batts for covering up.

Heat Loss from Air Is No Big Deal, Right?

No, it’s a huge deal. The photo (right) is of air streaming through recessed lights in a cathedral ceiling. I often and exhaustively speak about air sealing as if it were a universal good. And it is, right up there with brown ale and Avengers movies. My audit customers often look confused when I address their insulation questions by bringing up air barriers and air leakage. I mean, “Why are you talking about air leaks when I asked about the insulation?”

A Green Remodeling Training Project

Looking through the April issue of Remodeling magazine (after reading my own column in the issue), I ran across an article about John Tabor, a remodeler who used an addition to his own home to learn about green building and train his crews on technologies that they had not yet used.

(At Least) Four Things Are Wrong With This Picture

Posted on April 26,2015 by KSPmYvh9gx in batt

Last week we published this photo as part of our “What’s Wrong With This Picture?” series. The photo shows a substandard fiberglass insulation job that was representative of an entire residential subdivision that hoped to qualify for Energy Star. Examples like this show that quality control by HERS raters is a weak link in the Energy Star program.

What’s Wrong With This Insulation Job?

Posted on April 26,2015 by KSPmYvh9gx in batt

In many areas of the country, homes are receiving Energy Star labels they don’t deserve. Major errors like the ones shown in this photo are supposed to be caught by the HERS rater who performs third-party verification services. This home slipped through the cracks. The photo shows at least four errors serious enough to have prevented the home from receiving an Energy Star label. Can you spot them? Next week, we will post the answers that a Building America team, BIRA, came up with.

It’s OK to Skimp On Insulation, Icynene Says

Posted on April 26,2015 by user-756436 in building code

While energy experts often advise builders to exceed minimum code requirements for insulation, Icynene Incorporated, a manufacturer of open-cell spray polyurethane foam, is swimming against the tide. Surprisingly, Icynene is trying to convince builders to install less insulation than the code requires.

Attic Insulation Upgrades

Posted on April 26,2015 by Mike_Maines in conditioned attic

Two projects my company is currently working on involve a common problem: not enough insulation in the attic. Both homes are old; one dates from 1860, the other from 1705. In both cases we initially recommended insulating the rafter bays. In both cases, however, we were not able to get over homeowner biases against heating “storage spaces,” and instead opted for insulating the attic floor.
